CONFIG_VIRTIO_BLK_SCSI has been broken for about two years, as it
never set the QUEUE_FLAG_SCSI_PASSTHROUGH flag after that was
introduced.  I actually have a patch that I plan to send to remove
this support as it was a really idea to start with (speaking as
the person who had that idea back in the day).
